  5. How The Internet Works • Series of tubes

  6. How The Internet Works • When a web page is loaded, what happens? • Specifically, your PC is a ‘client’ • Client -> DNS lookup (what is ‘google.com’?) • 74.125.39.106 • Client asks server for webpage • Server returns a static webpage or generates one to show the client based on any parameters

  7. Organization • What happens where?! • Server • Returns a static HTML file, OR • Renders and returns a page using PHP or any other server technology • Perhaps look up data from an SQL database • Client • Decides how the HTML and CSS will appear to the user • Runs any Javascript the page includes

  8. Analogy Time! • Client: hungry man • HTML: bread • CSS: peanut butter and jelly • Javascript: sandwich is now cut in half • PHP: the sandwich’s maker • MySQL: kitchen cabinet • Server: kitchen

  9. HTML • HyperTextMarkup Language • NOT a programming language • Consists of ‘elements’ denoted in a <tag> structure • Document Object Model • How the browser understands the page in order to display it • A browser interprets this to display a webpage • Outline-esque

  10. Sample HTML • <p>Hello, world!</p>

  11. That Was Easy • Yes, it was • Used <p> element • Defines a paragraph • Opening and closing tags • Few exceptions • Other elements?

  12. Some other elements • <p> Paragraph • <a> Link (anchor) • <table> Table • <ul> Unordered list • <div> Divider • <span> Span • <br/> Line break* • Many others

  13. Special elements • <head> • Defines header of HTML file • <body> • Defines content of HTML file • <title> • Defines title of page

  14. HTML Standard • Standard exists so all browsers show (somewhat) same page • Different browsers use different rendering engines • Firefox: Gecko • Chrome, Safari: WebKit • IE: Trident • Opera: Presto • Standard is self-defining (XHTML) • <!doctype html>

  15. Example <!doctype html> <html lang=en-us> <head> <title>Our First Page</title> </head> <body> <p>Hello, world!</p> <p>This is a webpage.</p> </body> </html>

  16. Attributes • Help customize an element • id (unique identification for an element) • class (category) • Text field value • Picture size

  17. Case Study: <img> Tag • Some attributes: • Source URL • Alternate text • Dimensions • Source • Either URL or local image • Example: • <img src="http://imgs.xkcd.com/comics/orbiter.png"/>

  18. Assignment • Create a webpage comprised of a single HTML file • Requirements: • Use at least three tags in addition to the standard required tags: <html>, <head>, <body>, <title> • Must pass W3C Validation: http://validator.w3.org/#validate_by_upload • Due by midnight next Wednesday the 8th • Email to sduwebship@gmail.com

  19. Tips and Tricks • View source • Right click a page, ‘view source’ to see HTML • Text editors (please do not use a word proc) • Mac: TextWrangler • http://www.barebones.com/products/textwrangler/ • PC: Notepad++ • http://notepad-plus-plus.org/
